Abstract

Abstract: Serious soil erosion and frequently occurred sandstorm are the mainly ecological problems in arid zone of middle Ningxia. In order to control these series disasters, we chose typical pebbling farmland, traditional tillage farmland, artificial shrub land, fenced grasslands and shifting sandy land as the research objects, and wind erosion-resistance were comprehensively analyzed with TOPSIS method. The results showed that shrub land had the strongest ability to resist wind erosion, whose Ci was 0.674257. Traditional tillage farmland and shifting sandy land had relative weaker ability to resist wind erosion, with Ci respectively being 0.087007 and 0.003552. So the traditional tillage farmland and shifting sandy land are the main dust sources.
